The Sentinel Rack is a rack-mounted version of the popular Sentinel Pro range of online uninterruptible power supplies. Advanced double conversion technology provides the highest levels of reliability and protection for critical servers, data processing IT systems, and telecoms networks. Available in 1500 VA and 3000 VA versions, both products sit at just 380mm deep, making them the ideal choice to upgrade power in server rooms housing 600mm deep legacy racks.
For applications requiring several hours’ autonomy, the SER 3000 ER is fitted with a 6A battery charger and additional battery packs for extra runtime. These plug and play UPS systems are designed to fit standard 19 inch cabinet racks and incorporate a Cold Start feature that enables them to power up even if there isn’t a mains supply. Choose from a wide range of operating modes (i.e. Online, Eco, Smart Active, Standby Off, Frequency Converter) to boost performance and improve energy efficiency.
Different operating modes that can be programmed according to user requirements and the load to be powered have been introduced in order to reduce energy
The Sentinel Rack range has a deep discharge protection device to optimise battery life. Periodically the UPS carries out a battery efficiency test (which can also be manually
activated); its wide input voltage tolerance range helps to reduce battery usage and maintain performance over time.
Optional battery extension packs can be connected to increase UPS runtime. SER 3000 ER version is designed without internal batteries and a more powerful battery chargers to achieve longer runtimes.
